REVOLVING FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 301,182, dated July 1, 1884.

i0 @ZZ whom it may concern.-

Be it known that I, WILLIAM Tannen, a citizen of the United States, residing at Louisville, Kentucky, have invented new and useful Improvements in Revolving Fire-Arms, of which the following is a specification.

My invention relates to certain improvements in that class-of revolving fire-arms in which the cylinder is swung out laterally from the main frame and barrel during the operation of loading and expelling the empty cartridges, and is designed particularly for use with other improved parts, as described by me in applications iiled simultaneously herewith, and designated Cases A and B.

The object of the present invention is to provide a simple `and secure means of detachably securing the swinging fra-me carrying the cylinder to the main frame of the pistol in such a way as to hold the parts lirmly in place during discharge, and at the same time be easily disconnected when desired.

The invention consists of a pin or bar formed with or secured to the swinging frame carry- -ing the cylinder, and adapted to take into and revolve in an opening in the main frame beneath the cylinder, said opening being provided with a spring-actuated catch for holding the pin in position.

`In order to enable those skilled in the art to make and use my invention, I will now prowith the accompanying drawings, in which* Figure l is a side view, partly in section, of a pistol embodying my invention. Fig. 2 .is a plan view of the same. Fig. 3 is a longitudinal section ofthe rotating pin and fastening device. Fig. 4 is a section through line x m of Fig. 3. i

A in these drawings designates the main frame or body ofthe weapon, into `which is bored a suitable opening, a, for the reception of the pin, on which the' swinging frame B rotates, the forni and arrangement of which frame and of the several parts shown in the drawings, but not particularly mentioned herein, are clearly denedfin applications filed herewith. rIlhe pivot'and means of support of the frame B are formed by the projection b.` This projection is formed integral `with or,

'4 if desired, secured in any one of the ways well known in the art to the frame B, and is provided at any suitable point on the portion entering the socket c with a circumferential groove, c, for the reception of the interlocking portion d of the pin C. By the peculiar and novel arrangement of this retaining-pin O, I provide a fastening which holds the rotating frame, through the media of the projection b,iir1nly in place, and at the same time it may be easily released by a pressure on the exposed milled end g, when it is desired to withdraw the pin from the socket. The locking 'in place ofthe projection is accomplished by the enlarged part d of the pin C being placed in the groove of the said projection, into which it iits snugly. To accommodate this pin C, I bore into the frame A an opening-preferably in the left-hand side of the pistol-large enough for the passage of the disk d, which opening extends half the thickness of the said disk beyond the center of the frame, so as to bring the disk approximately over the center of the extension I). Besides this hole, I bore another for the smaller portion, c, of the pin G, and still another for the reception of the button g. A spring, f, is provided, the resiliency of which keeps the pin in the position shown in Fig. 4 by bearing against the screw-stud D, and forcing the disk d against the shoulder h. The cap D has a central opening for the passage of the pin 5, and has, as shown, external screw-threads, interlocking with coincident screw-threads on the inner face of the opening. The righthand end of the pin G is provided with a milled screw-cap, g, which is adapted to be pressed by the finger in releasing the projection b from the disk d. The opening at this a length corresponding with the distance necessarily traveled by the disk d in order to free itself from the pin b.

Having described my invention, what I claim is l. In a revolving fire-arm, the swinging portion B of the frame, provided with a cylindrical rearward projection or arm, I), having an annular channel, c, in combination with the main or stationary frame A, provided with end into which the cap is forced should be of 9o IOO a longitudinal recess or seat, a, adaptedv to receive the arm I), an d the spring-actuated catchbolt C, arranged to interlock with the groove frame B, provided with extension or arm I), c, whereby the swinging,` portion is free to rohaving annular groove c, substantially as and tate upon the extension or zii-n1 b, or to be refor the purpose set forth.
